Ingredients List
Gathering high-quality ingredients is the first step to an unforgettable Cajun Shrimp Pasta. Here’s what you’ll need, complete with sensory notes and smart substitutions.
- For the Cajun Seasoning (or 2.5 tbsp store-bought):
- 2 tsp smoked paprika (for deep, smoky aroma)
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp dried oregano
- 1 tsp dried thyme
- 1/2 to 1 tsp cayenne pepper (adjust for heat)
- 1/2 tsp black pepper
- 1/2 tsp salt
- For the Pasta & Proteins:
- 12 oz fettuccine or linguine (substitute with whole wheat or gluten-free pasta)
- 1 lb large shrimp, peeled and deveined (look for firm, translucent flesh with a mild sea scent)
- 12 oz andouille sausage, sliced into 1/4-inch coins (substitute with smoked kielbasa or chorizo for a different smokiness)
- For the Aromatic Base:
- 1 tbsp olive oil or unsalted butter
- 1 medium yellow onion, finely diced
- 1 red bell pepper, thinly sliced (adds sweet crunch and vibrant color)
- 3-4 cloves garlic, minced (the fragrant heart of the sauce)

- 2 cups heavy cream (for ultimate richness; substitute with half-and-half or full-fat coconut milk for a lighter/dairy-free version)
- 1 cup low-sodium chicken broth
- 1 cup freshly grated Parmesan cheese (the nutty, salty key to a cohesive sauce)
- 2 tbsp unsalted butter
- Salt and black pepper to taste

Step-by-Step Instructions
Step 1: Prepare Your Ingredients
This is your “kitchen victory lap.” Pat your shrimp completely dry with paper towels—this is non-negotiable for a good sear. Toss them in 1 tablespoon of the Cajun seasoning. Slice the andouille sausage, dice the onion, slice the bell pepper, and mince the garlic. Grate your Parmesan cheese if you haven’t bought it pre-grated. Having everything within arm’s reach transforms cooking from a stressful race into a enjoyable, rhythmic process.
Step 2: Cook the Pasta
Bring a large pot of generously salted water to a rolling boil. Add your fettuccine and cook according to package directions for al dente texture—usually about 8-10 minutes. We want the pasta to have a slight bite, as it will continue to cook slightly in the sauce later. Before draining, reserve about 1 cup of the starchy pasta water. This liquid gold is your secret weapon for adjusting sauce consistency at the end.
Step 3: Sear the Andouille Sausage
While the pasta cooks, heat a large, heavy-bottomed skillet or Dutch oven over medium-high heat. No oil is needed initially due to the sausage’s fat. Add the sliced andouille in a single layer and cook for 2-3 minutes per side until beautifully browned and crispy around the edges. That fond (the browned bits stuck to the pan) is pure flavor. Remove the sausage with a slotted spoon and set it aside on a plate, leaving the rendered fat in the pan.
Step 4: Cook the Shrimp
In the same skillet with the sausage drippings, add the shrimp in a single layer. Cook for just 1-2 minutes per side, until they turn pink and opaque with a slight curl. They cook incredibly fast! Overcooking leads to rubbery shrimp, so be vigilant. Remove them immediately and place them with the sausage. They’ll finish warming through in the sauce later.
Step 5: Build the Creamy Cajun Sauce
Lower the heat to medium. Add 1 tbsp of olive oil or butter to the skillet. Sauté the diced onion and sliced bell pepper for 4-5 minutes until softened. Add the minced garlic and the remaining Cajun seasoning, stirring for 30 seconds until incredibly fragrant. Pour in the chicken broth to deglaze the pan, scraping up all those delicious browned bits. Let it simmer for 2 minutes to reduce slightly. Stir in the heavy cream and bring to a gentle simmer—do not let it boil vigorously. Whisk in the grated Parmesan cheese and 2 tbsp of butter until the sauce is smooth, creamy, and slightly thickened. Season with salt and pepper to taste.
Step 6: Combine and Serve
Add the drained al dente pasta directly to the creamy sauce. Toss everything together, allowing the pasta to soak up the sauce for a minute. If the sauce seems too thick, add a splash of the reserved pasta water to loosen it. Gently fold in the reserved andouille sausage and shrimp, heating through for another minute. Finish with a generous sprinkle of fresh chopped parsley or green onions for a pop of color and freshness. Serve immediately while hot and creamy.

Healthier Alternatives
Love the flavor but want a lighter twist? These swaps maintain the soul of the dish while adjusting the nutritional profile.
- Lighter Cream Base: Swap heavy cream for half-and-half, whole milk, or a blend of milk and a tablespoon of flour for thickening. For a dairy-free version, full-fat canned coconut milk adds a lovely richness.
- Leaner Protein: Use chicken breast or turkey sausage instead of andouille. For the shrimp, they are already a lean, excellent choice.
- Boost Veggies: Double the bell peppers and add sliced mushrooms, spinach, or zucchini to increase fiber and volume without many extra calories.
- Whole Grain or Legume Pasta: Use whole wheat, chickpea, or lentil pasta for added protein and fiber, which helps you feel fuller longer.
- Control Sodium: Use low-sodium broth, limit added salt, and look for lower-sodium andouille sausage.
Serving Suggestions
This pasta is a star on its own, but the right accompaniments can turn it into a full-blown Southern-inspired feast.
- To Balance the Richness: A simple, crisp green salad with a tangy vinaigrette (like lemon or red wine vinegar) is perfect.
- The Classic Side: Warm, buttery garlic bread or cornbread to soak up every last drop of that creamy Cajun sauce.
- Vegetable Pairings: Sautéed green beans, roasted asparagus, or a charred corn salad.
- Beverage Pairings: A cold, crisp lager or pilsner, a slightly sweet iced tea, or a fruity Zinfandel or Grenache wine can stand up to the spices.
